A.F.C.I. breakers have tens of thousands of arc signatures programmed in so it does not trip when it sees this type of arcing. Like different vacuum cleaners etc. I have troubleshot afci breakers trip intermittently from one single led trim and a coffee maker with a coffee grinder built in. And the others that the cause of the tripping was never found. Well after a certain amount of trouble shooting you just swap it for a normal breaker. But if you are installing them new or remodel and they trip, you probably have neutral from another circuit tied in with your circuit. A tip how to find this, in the panel have just your afci circuit on and disconnect another circuits neutral then retry. Do this one by one until it holds, then atleast now you know what two circuits are tied together. Usually it will be in a multi gang switch box. Or you can do that process backwards, have all neutrals disconnected except for your afci circuits neutral, and touch each neutral to the neutral bar one by one. If you think you may damage the breaker the other way. I heard siemens intelli arc tool was no good. Hope this helps someone. Trump 2020.
"Well after a certain amount of trouble shooting you just swap it for a normal breaker." What if the problem was an intermittent arc? Then the AFCI was doing it's job and so the house burns down 6 months later. That's like having a fuse blowing because of an unknown and unlocatable overload and so you just put a penny in under the fuse.
Probably because of the length of the house wiring resonates around 100KHz. I wonder if those plug in intercoms which work around that frequency (or it's harmonics) would trip an AFCI? Maybe something to consider.
The AFCI breakers have 2 neutrals hooked up, load, and the pigtail/push on. Is the non-load neutral connection used to create a parallel circuit within the breaker itself to power the pcb to enable the in band signal processing on the waveforms?
That is more of what they do not how they work. what does the circuit that monitors this look like? is it microprocessor based or analog? Perhaps you should retitle this video
The Electric Academy its called radio waves in a certain frequency thats causes the microprocessor to break the circuit. So coffee grinders and magnetrons/ microwaves tend to make them trip as well as cb radios and other devices that produce radio interference of a certain band modulation and intensity. Didnt like it because you never answered the question. I was waiting on you to describe the faries in the breaker that trip the breaker.

Thank you for showing the waveforms. This satisfies my understanding that the past sites and videos couldn’t explain

@@MandrewP yep
Thanks your videos so helpful learn a lot from you makes so much easier
Good presentation. The frequency the AFCI is looking for is 100KHz
Probably because of the length of the house wiring resonates around 100KHz. I wonder if those plug in intercoms which work around that frequency (or it's harmonics) would trip an AFCI? Maybe something to consider.
Radio frequencies
The AFCI breakers have 2 neutrals hooked up, load, and the pigtail/push on. Is the non-load neutral connection used to create a parallel circuit within the breaker itself to power the pcb to enable the in band signal processing on the waveforms?
neutral is passing through the breaker back to the neutral bar
Thanks for covering this topic.
Superb explanation !!!! thanks
Great video. Thanks
Thanks
what do u mean it has to be mechanically protected?
would that mean it would have to run mc or ac instead of romex?
It means conduit or armored cable
Does afci breakers trips when overloaded as well?
All breakers trip for overloads and short circuits.
My vacuum trips it immediately
You still didn't cover how they work. You just said they have a circuit inside.
He said it works by monitoring the waveform. What's he got to do, break down how a microprocessor works too? Smh
I can save you 15 minutes: They don't.
Just go to 6:36 and save some time.
That is more of what they do not how they work. what does the circuit that monitors this look like? is it microprocessor based or analog? Perhaps you should retitle this video
Gonna save everyone some time. Dont waste 15 minutes.
dekonfrost7 is you mean don’t waste 15 minutes? Sorry you didn’t like it.
